Chapter 34. Authentication Proxy

To support integration of Evergreen with organizational authentication systems, and to reduce the proliferation of user names and passwords, Evergreen offers a service called open-ils.auth_proxy. If you enable the service, open-ils.auth_proxy supports different authentication mechanisms that implement the authenticate method. You can define a chain of these authentication mechanisms to be tried in order within the <authenticators> element of the opensrf.xml configuration file, with the option of falling back to the native mode that uses Evergreen’s internal method of password authentication.

This service only provides authentication. There is no support for automatic provisioning of accounts. To authenticate using any authentication system, the user account must first be defined in the Evergreen database. The user will be authenticated based on the Evergreen username and must match the user’s ID on the authentication system.

In order to activate Authentication Proxy, the Evergreen system administrator will need to complete the following steps:

Edit opensrf.xml.

Set the open-ils.auth_proxy app settings enabled tag to true

Add the authenticator to the list of authenticators or edit the existing example authenticator:
